Discriminative approaches [7,24] for hand pose estimation tend to require large datasets of training examples, synthetic, realistic or combined [7]. The current lack of training data makes the 3D hand+ object pose estimation very challenging. First, we present a single-view single-object 6D pose estimation method, which we use to generate 6D object pose hypotheses. 3D pose estimation is always an active but challenging task for object detection in remote sensing images. While our work stems from the same observation that pose and shape are closely related, We are releasing the dataset of keypoint-labeled transparent objects for use by the research community. Hi, In regards the 3D Object Pose Estimation ‘camera feed’ app: If we trained our own model for a different object than the dolly, and generated a codebook, is this all that needs to be done? The 3D pose estimation model used in this application is based on the work by Sundermeyer et al. Two main innovations enable our system to achieve real-time robust and accurate op-eration. The method explodes the rich information obtained by a projective Animation 1: Example of 3D object rotation using marker tracking. Their main limitations are the limited set of object poses they accept, and the large training database and time.
